Sqrt 80n^2 = sqrt 40x2xnxn = sqrt 20x2x2xnxn = sqrt 10x2x2x2xnxn = sqrt 5x2x2x2x2xnxn

Pull out numbers and letters in groups of 2

2x sqrt 5x2x2xnxn
2x2x sqrt 5xnxn
2x2xnx sqrt 5

Multiply the numbers and letters on the outside of the radical

4n x sqrt 5 is the final answer.

Can someone please explain The measure of angle A to the nearest tenth of a degree is:

Ratling [72]

Answer:

A =19.5

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin A= opp/ hyp

sin A = 3/9

Take the inverse sin of each side

sin ^-1 sin A = sin ^-1 (3/9)

A =19.47122063

To the nearest tenth of a degree

A =19.5

The length of a square is 256m and the breadth is 238m what is the perimeter

nikitadnepr [17]

The perimeter is 988 meters

Further explanation:

The given square has different length and breadth which means that the given square is a rectangle.

The formula for perimeter of a rectangle is:

$P=2L+2W$

Given

Length=L=256m

Breadth=W=238m

Putting the values in the formula:

$P=2(256)+2(238)\\=512+476\\=988\ meters$

The perimeter is 988 meters.
